how to obtain green background for some text?

[Gernot Hassenpflug]

Hello,

I have used boxquote.el a lot for marking cited text, but am searching
for a manner in which to mark text, particularly code, in my posting
with a green background. Searches for "background color",
"highlighting", and similar did not lead to any useful links for me
either for this newsgroup or the comp.text.tex group. I am hoping
someone here knows how to do this in gnus. I have also tried emacs's
text properties from the edit menu, but none of the font
foreground/background options are available in editing articles for
newsgroups.

Any help or hints appreciated.
